中性恒星核在核密度或以上时，由于它们具有不同的质量和相互作用，可以用带正电的重子核和带负电的电子流体来描述。基于引力坍缩或脉动重子核的简化模型，我们近似地积分了Einstein-Maxwell方程和完全简并电子流体的数目守恒和能量动量守恒方程。我们展示了在重子核边界产生电子-正电子对的可能的电过程，并计算了电子-正电子对的数目和能量。这可能与理解超新星和伽马射线爆发的能量来源有关。
Neutral stellar core at or over nuclear densities is described by a positive charged baryon core and negative charged electron fluid since they possess different masses and interactions. Based on a simplified model of a gravitationally collapsing or pulsating baryon core, we approximately integrate the Einstein-Maxwell equations and the equations for the number and energy-momentum conservation of complete degenerate electron fluid. We show possible electric processes that lead to the production of electron-positron pairs in the boundary of a baryon core and calculate the number and energy of electron-positron pairs. This can be relevant for understanding the energetic sources of supernovae and gamma-ray bursts.
